Monitoring battery capacity
What is available to get a true read on battery state. Running 2-GC2 batteries. The monitor panel isn't real helpful at showing condition with a green, yellow and red light. Don't want to pull them do...

^^^^ Chart above is for a battery with a modest load. Open circuit resting voltage is higher.
OP, get a voltmeter. Biggest thing to know is when to start recharging. 12.20 or less is time for recharge. To 90% charge is fairly fast and the last 10% can take 6 to 10+ hours. So you are not really looking for 100% while in use or charging on a generator.
Next you need to review your charging system to see if you need to run the generator 2 hours or 20 hours to get close to 90%.
Once you get the hang of it and discover what voltages those lights mean they actually become quite useful.
